Installing samba-dev:i386 breaks Ubuntu 22.04.1.

[Keith David Bershatsky]

Ubuntu 22.04.1 LTS: sudo apt install samba-dev:i386

Installs a bunch of stuff relating to the libreoffice suite and at the tail end of the installation of the above-named package, apt removes a plethora of absolutely essential packages need to use Ubuntu, including, but not limited to the entire desktop, gdm, and the ability to access the internet to download any packages with apt. The entire virtual machine (other than a rudimentary terminal when booting up) was broken after installing samba-dev:i386 and needed to be restored from a backup. Please either have apt refuse to install samba-dev:i386, or at the very least, provide a complete list of essential packages that will be removed with a mandatory interactive confirmation to proceed.

I had tried to install this package, which is one of the dependencies for building Wine from source:

Wine ... configure: 32-bit/64-bit libnetapi not found, Samba NetAPI won't be supported.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1993081

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

[Keith David Bershatsky (lawlist)]

Thank you for guiding me to create better bug reports in the future. In the context of this particular issue, the entire virtual machine becomes unusable and it would be impossible given my current skill level to get the terminal output or a log off of the VM in order to submit a bug report. Even a common text editor such as gedit disappears. Here is the list of what will be removed and installed, without actually proceeding with the installation of this i386 package:

I believe you are trying to install samba-dev:i386 in amd64 system, am I right? I tried to do the same in a LXD container and it indeed removes a bunch of important packages, like ubuntu-minimal and netplan.io. However, i386 is not an officially supported architecture since Ubuntu Eoan 19.10 [1], which means that not all packages in the archive are built in i386 just a subset of them. When you try to install a package built for a foreign architecture, in this case i386 which is not fully supported, this type of thing might happen.

Regarding the apt behavior, I do not see a problem here. I got a list of all package that would be removed (including the ones I think it is important to run the system) and it asked for confirmation ([Y/n]). If you call apt in a non-interactive mode, passing -y option then that's the user choice.

TBH I do not see a real issue here. If your final goal is to use wine, it is available in the archive since Ubuntu Bionic 18.04 [2]. You could consider using the Debian package in the archive instead of compiling it by yourself, but I do understand you might have other reasons to compile it from source.

Q: I believe you are trying to install samba-dev:i386 in amd64 system, am I right?

A: Yes, that is correct.

The dependencies for building Wine from source are listed on the Winehq wiki page:

https://wiki.winehq.org/Building_Wine

In the context of this particular bug report, the applicable dependency listed in the above-mentioned wiki, and also complained about by the configure script of Wine prior to building from source, is as follows:

libnetapi | samba-dev | samba-devel | smbclient | Networking | Rarely needed.

In my opinion, the developers of the samba-dev:i386 package should consciously make a decision whether it is absolutely necessary to leave the user with a broken installation of Ubuntu in order to properly install this package. If that is the case, then there should be an additional warning beyond merely which packages will be removed. E.g.,

WARNING: Installing samba-dev:i386 will remove packages essential to using a desktop GUI interface such as Gnome, including, but not limited to accessing the internet, submitting bug reports with apport, using a text editor such as gedit, installing packages with apt (due to no internet access), etc.

The developers of the samba-dev:i386 package should ask themselves whether it is absolutely necessary to remove things like gdm, apport, gedit, gnome desktop, etc.

There are just too many unsuspecting users of Ubuntu 22.04 LTS who will try to satisfy the dependencies of popular programs such as building Wine from source, and said users will assume that the worst that can happen is that it might be necessary to run: sudo apt remove ... or fix-broken, etc. In this case, using apt to fix anything is impossible because there is no way to download and install the packages that are being removed.

In my particular use case, I have consciously decided to build Wine from source for a variety of reasons, including, but not limited to have the benefit of the latest bug fixes and enhancements.

Looks like the culprit here is python3, as doing

  apt install python3:i386

causes the removal of several important packages. This in a Jammy LXD container and after doing `dpkg --add-architecture i386`.

The python3 package is marked Multi-Arch: allowed, so I would expect the i386 package to be co-installable without breaking the world, but I'm unsure on how this is supposed to be supported in Ubuntu (as Lucas mentioned i386 is not officially supported). Maybe we're just inheriting the Multi-Arch settings from Debian? I added a python3 task, let's see if we can get more information from a Python maintainer.

Relevant output (use `-o Debug::pkgProblemResolver=yes` for more verbosity):

Officially closing as Won't Fix since i386 is not an officially supported arch, and it seems there is not any more desire for this.

Please let me know if this should stay open.

[Keith David Bershatsky (lawlist)]

Understood ... please go ahead and close this bug report. Thank you.
